Any way to set an option to lock the icons on the dock...When you have kids, they are constantly deleting them.
Also, grown ups that are not used to a track pad seem to accidentally remove icons as well.
Personally it would be great to have the option in Settings to lock the icon bar so as to "Do not allow icons to be Pinned and do not allow removing of Pinned icons".
